Interesting. It seems that the problem is caused by the OpenMP stack overflowing. To fix, set the OMP_STACKSIZE variable to something large -- say, 2M.

The calculation still may fail due to a frequency mismatch, but this is not anything to worry about -- just numerical noise from changing gfortran versions, I think.

Setting the OMP_STACKSIZE=2M fixed the seg fault, thank you.

Is the following failure what you were referring to from mismatched gfortrans?

Yep!
